Making a PRECISE lead screw nut | CRAIG'S WORKSHOP

It's time to look at the Herless 14x40* lathe again. It's got large amounts of backlash in the compound and crossfeed, so let's pull it apart, do some measuring and find out which parts need remaking.

* I started work on this lathe in the previous video, please see that one for the backstory.

Enjoy!
